摘要

当射电射线穿过大气层时，由于大气层的存在而被驱散。这种效应用散度系数a来衡量，并推导出了在光滑球形地球条件下，直射光的散度系数D1和反射光的散度系数D的一般公式。举例来说，在“指数”大气(对流层)的一些典型情况下，给出了DI和Dz。

Defocusing of radio rays by the troposphere

When radio rays pass through t he atmosphere, they are defoc Llsed due to its presence. This effect is measu red by the divergence coefficient a nd general formulas are derived for D1, the divergence coefficient of t he direct ray, and D" the divergence coefficient of the reflected rayassuming a smooth spherical earth . As examples, DI and Dz are shown for some typical cases with an "exponential" atmosphere (troposphere).
